Targeting multiple layout handles in layout XML

Question

I have a custom controller accessed at the path /custommodule/customer/info which is loading the 2columns-left.phtml template on the root node as follows:

<custommodule_customer_info>
    <reference name="root">
        <action method="setTemplate"><template>page/2columns-left.phtml</template></action>
    </reference>
</custommodule_customer_info>

What I would like to do is update the root template for customers who are not logged in, something such as:

<customer_logged_out>
    <custommodule_customer_info>
        <reference name="root">
            <action method="setTemplate"><template>page/1column.phtml</template></action>
        </reference>
    </custommodule_customer_info>
</customer_logged_out>

I understand that I can't target multiple layout handles in this fashion, but the intent should be clear; update the root template for this layout handle while customers are not logged in.

I had thought that I could target my controller's handle with the following:

<customer_logged_out>
    <reference name="custommodule_customer_info">
        <reference name="root">
            <action method="setTemplate"><template>page/1column.phtml</template></action>
        </reference>
    </reference>
</customer_logged_out>

This indeed does update the root template with the 1column.phtml template, but it is doing so on what appears to be all pages instead of just the page targeted in my reference node.

I have tried several permutations of this layout update, but none seem to work. How can I target this one layout handle while at the same time using the customer_logged_out layout handle?

-- edit -- To be clear, this is actually a third-party module.

Answer 1

Since you are using your own controller you don't need to only use the default handles. Based on the logged in status you could add in your infoAction method

 $this->getLayout()->getUpdate()->addHandle('mymodule_customer_info_logged_in');

or

 $this->getLayout()->getUpdate()->addHandle('mymodule_customer_info_logged_out');

and then in your layout.xml file use

<mymodule_customer_info_logged_in>

and

<mymodule_customer_info_logged_out>

-- addition after your edit below --

Seeing that you don't want to edit the controller (since it is a 3rd party extension), I would create a separate extension that only observes controller_action_layout_load_before

    $update = $observer->getEvent()->getLayout()->getUpdate();
    $handles = $update->getHandles();

    if (in_array('custommodule_customer_info', $handles)) {

        //code to add the custom handles based on login
    }

Alan Storm has answered something similair like this:

You can use a helper to do your logic of checking whether the custom in logged in.

<action method="setTemplate">
    <template helper="mymodule/myhelper/switchTemplateIf"/>
</action>

It will call Mage::helper('mymodule/myhelper')->switchTemplateIf(); In that helper you can decide to switch the template or just keep it like this.

I believe it sets the template to whatever you return in that function.

It would look something like this:

public function switchTemplateIf() {
    if (Mage::helper('customer')->isLoggedIn()) {
        return 'page/1column.phtml';
    } else {
        return 'page/2column-right.phtml';
    }
}

I recently needed this kind of functionality & it was getting difficult adding more & more layout handles for all the different combinations of existing layout handles, so i created a magento extension to add the ability of targeting multiple layout handles from the layout xml directly.

Here's the link to the extension- https://github.com/mridul89/MultipleHandles.git

You would use it like this-

<customer_logged_out ifhandle="custommodule_customer_info">
    <reference name="root">
        <action method="setTemplate"><template>page/1column.phtml</template></action>
    </reference>
</customer_logged_out>

This will tell magento to only use this particular customer_logged_out layout handle if custommodule_customer_info layout handle is also present.
